Use multithreading, plus make the non-float / non-separate luma calculations faster by avoiding byte->float->byte conversions back and forth. On a 4K resolution sequencer display, time taken to calculate the waveform (Windows, Ryzen 5950X): - regular images: 127.0ms -> 6.4ms - regular images, separate colors: 160.3ms -> 13.1ms - float images: 86.2ms -> 11.1ms - float images, separate colors: 162.9ms -> 17.4ms This also fixes curious "one black pixel row" in the middle of the waveform, which was caused by the code spreading 256 possible luma values over "off by one" vertical range: Pull Request: https://projects.blender.org/blender/blender/pulls/115579
